Hey all, I have a very lethargic sick betta on my hands, and am wondering if I could get advice as to how to treat him? His appearance is healthy, he is just very tired, and won't eat. I am worried that he has some form of poisoning, so I have increased the amount of water changes he gets, but that is all I really know to do. If I could get some help, that would really be great, especially because I love him to bits (would the salt treatment help?)

Thanks heaps! B.
